Pluto, also called Pluto the Pup, is a cartoon character created in 1930 at Walt Disney Productions. The dog was named after the discovery of Pluto, a few months earlier.
In 1930 he played a bloodhound in a cartoon by Disney called "The Chain Gang". Next he played Minnie Mouse's dog in the cartoon called "Picnic." Then he finally became Pluto I think a few years later.
Because he had a dog as a child named Pluto.
